Wei Liangyou 534

Classification:

High latitude or high altitude areas (northern Hubei, southern Henan, northern Anhui) and hilly and mountainous areas are suitable for sowing from late April to late May, Jianghan Plain, Chaohu Plain, Lishiahe Plain and middle and low latitudes in Jiangxi and Hunan are suitable for sowing in mid and late May. The soaking time is not less than 12 hours, the first soaking time is about 8 hours, the water is taken and filtered dry, and then the water is changed to soak for about 4 hours. Do a good job in seedling management and cultivate strong seedlings.

Rice

Hotline:

1, timely sow, thin sow strong seedlings to build seedling rack.

2, reasonable dense planting, to ensure the basic seedlings.

The amount of seed used for transplanting seedlings per mu is 1kg/mu, and the transplanting density in the field is 5 × 8 inches or 4 × 9 inches. Double transplanting (two grain seedlings). The amount of seed used for direct seeding mu is 1.75-2kg/mu, and that for seedling throwing mu is 1.5kg/mu. Reasonable dense planting, to ensure that mu of basic seedlings up to more than 60000.

3, formula fertilization, to ensure stable and high yield.

Nitrogen, phosphorus and potassium are applied in a balanced manner at a ratio of 1:0.5:1. It is advisable to use 12kg of pure nitrogen per mu. Base fertilizer is applied heavily, top dressing is applied early, and ear fertilizer is applied skillfully. It is suggested that compound fertilizer 40.00 kg-45.00 kg with a content of more than 45% should be applied per mu in plain lake area, and compound fertilizer 45.00 kg-50.00 kg should be applied per mu in hilly mountain area as base fertilizer. Urea 10.00 kg-12.50 kg/mu should be applied about 5 days after transplanting or throwing seedlings, urea 10kg should be applied to two leaves and one mu of seedlings directly, and urea 5.00 kg-7.50 kg should be applied to one mu as tillering fertilizer one week later. After rewatering in the sun-dried field (stage 3-4 of young spike differentiation), 20kg of potash fertilizer shall be applied per mu. If the seedling condition is weak, 20kg/mu of compound fertilizer shall be applied as spike fertilizer. In the later stage, it is not recommended to apply nitrogen fertilizer in favor of compound fertilizer or potash fertilizer.

4, scientific management of water, improve the quality of rice.

Transplanting or throwing seedlings to the field, deep water live stump green, shallow water irrigation frequently to promote tillering, enough seedlings timely drainage drying field, booting to heading flowering stage field irrigation deep water, filling stage to keep the field with water, 7 to 10 days before harvest drainage, prevent premature senility, improve rice quality.

5, pay attention to the prevention and control of diseases and pests, and strive to become a high standard demonstration field.

Rice thrips and southern black-streaked dwarf shrinkage disease were prevented during the seedling stage. According to the disease and insect forecast, timely application of pesticides was used to prevent and control diseases and insect pests such as stem borer, rice leaf roller, sheath blight and rice false smut during the field stage. Coastal areas, flooded paddy fields, etc. should be promptly prevented from the occurrence of diseases such as bacterial blight and sliver disease.
